` To @ZZ whom, it 11i/foy 00h/007%:

. Be it known that I, ROBERT L. PARKER, a

citizen of the United States, residing at Merkel, in the county ofTaylorand State of Texas, have invented a new and useful CombinedCotton-Chopper and Oultivator, of which the following is aspecification.

My invention relates to improvements in combined cotton-choppers andcultivators; xo and the object in view is to provide a simple anddurable construction adapted for c ultivating the growing cotton or tothin out the row of plants, provision being made for throwing thechopping devices out of gear when I5 the implement is to be used forcultivating purposes. l

Vith these ends in view the invention consists in the novel combinationof element-s and in the construction and arrangement of parts,\vhichwill be hereinafter fully described and claimed.

In the drawings, Figure 1 is a perspective view of a combined cultivatorand cottonchopper constructed in accordance with my invention. Fig. 2 isa plan view thereof. Fig. 3 is a vertical transverse sectional elevationon the plane indicated by the dotted line 3 3 of Fig. 2. Fig. 4 is adetail sectional elevation illustrating the chopper-driving shaft andthe clutch mechanism by Which the chopper devices may be thrown 'into orout of gear with one of the carrying-wheels. Fig. 5 is a longitudinalsectional elevation on the plane indicated by the dotted line 5 5 ofFig. 3. Fig. (i is a detail view illustrating a modified type of drivingmechanism which may be used between one of the machine-carrying wheelsand the chopper-driving shaft.

l The same reference-numerals indicate like and corresponding parts ineach of theseveral figures of the drawings.

In carrying my invention into practice I employ a supporting-frame 10,which is in the form of an arch furnished with extensions whichconstitute the hangers 11, adapted to carry the short axles 12, saidaxles supporting the machine carrying wheels and the movablecross-heads, by which the cultivatorbeams are connected operatively withthe framework. The axles 12 are fitted in the Serial No.714,799 (Nomodel.)

hangers 11 of the frame, so as to protrude at both ends from saidhangers, and thus each axle has one end prolonged beyond the outer sideof the frame and beyond the inner part of the hanger ll, in which it ismounted.

The carrying-Wheels 13 may be of any suitable construction, and they arefitted loosely on the axles 12.

- 14 l5 designate the cross-heads,tted loosely on the inner ends of theaxles, and each crosshead is supported individually by one axle, so asto be adjustable jointly with the other cross-head. Each of thecross-heads is cast in a "single piece of metal to provide the iatcurved plate 1G at its front end and the bifurc'ated jaw 17 at the rearend, said curved plate 16 of each cross-head being provided with aseries of apertures 16a. heads 14C 15 are furthermore provided withtransverse openings 1S at points between the The crossjaws 17 and theattachment of said crossheads to the axles, and between the crossheadsis disposed a transverse bearing-block 19, which is furnished at itsends with trunnions or studs 20, adapted to iit in the openings 18 ofthe cross-heads, whereby the bearing-block is supported by and betweenthe cross-heads for adjustment therewith. This bearing-block is providedat a point intermediate its length with a shaft-bearing 2l,

`adapted to receive the frontend of the chopper-shaft.

A suitable draft-tongue 22 is connected to the frame or arch 10, and onthis tongue is mounted a doubletree 22, to the ends of which areconnected stay-chains 23, that are fastened adj ustably to theperforated plates 1G of the two cross-heads, thus transmitting a part ofthe draft from the doubletree to the crossheads, which are mounted onthe arch or framework.

The'cultivator-beams 24: have their front ends fitted in the jaws 17 ofthe cross-head, and said beams and cross-heads are pivoted directlytogether by the vertical bolts 24, Said beams carry series ofspring-teeth 25, and the beam may be raised or lowered by the provisionof suitable adjusting-levers 26, which are mounted upon the frame orarch 10 within convenient reach of the driver, said IOO adjusting-levershaving chains 2G, connected operatively to the cultivator-beams 24.

A cross-rail 27is secured at its ends to the cultivator-beams 24, saidrail lying a suitable distance in rear of and parallel to the bearing-block 19, which is supported by the crossheads 14 15, and saidbearing-rail is provided with a shaft-opening 27, which is disposed inalinement with the shaft-opening 21 of the bearing-block. A rockingchopper-shaft 28 is arranged in a substantially horizontal positionbetween the pair of cultivator-beams, and the ends of this shaft arefitted loosely in the opening 21 of the bearing-block and the opening27nr of the cross-raihwhereby the chopper-shaft is supported in properposition by devices which are carried by the crossheads and thecultivator-beams, respectively. Near its front end this chopper-shaft isprovided with a crank 29, and at a point intermediate of its length saidshaft 28 is formed with a transverse opening 30. In this opening isfitted a blade-carrying bar 31, which is adapted to be held firmly inplace on the chopper-shaft by a suitable clamping devicesuch, forexample, as a binding-screw 31-- and at its lower end this bar 3l isprovided with a chopping blade or hoe 32, which may be of any preferredconstruction.

The chopper-shaft is adapted to be positively rocked or vibrated byoperative connections with one of the carrying-wheels 13 of the machine,and one element of the chopperdriving mechanism is a horizontal shaft33,

disposed transversely to the line of draft and supported on the arch orframe 10 of the machine. The chopper-driving shaft is journaled in oneor more bearings 34, and said bearing or bearings may be provided withslots 35, adapted to receive bolts 3G, by which the bearings may befastened securely and adjnstably on the arch or frame 10 for the purposeof adjusting the bearing to take up slack inthedriving-gearpresentlydescribed. This driving-shaft 33 is provided, ata point on one side of its bearing,with a clutch-face 37 which is in theform of a sleeve fixed securely to said shaft 33, and mounted loosely onthe shaft, adjacent to the clutchface 37, is a shiftable driving-clutch38, which has operative connections with the rocking chopper-shaft. Thedriving-clutch 38 is mounted `loosely on the inner part of the shaftwhich is disposed over the chopper-shaft 28, and said driving-clutch hasa sleeve cast in a single piece with a head 39 and a crank-disk 40, saidhead and disk being properly spaced apart and near the respective endsof the clutch-sleeve to accommodate a shipping-lever by which the clutchmay be moved into and out of engagement with the clutch-face 37, whichis fast with the driving-shaft 33. The crank-disk 40 at the inner end ofthe driving-clutch is provided with a series of apertures 41, in eitherof Which may be secured the Wrist-pin 42, thus making the Wrist-pinoccupy shiftable engagement with the drivin g-clutch. To this Wrist-pinis .loosely connected the upper end of a pitman 43, which is disposed ina vertical position at one side ofthe arch orf rame 10, and the lowerend of this pitman is connected loosely with the crank 29 ofthechopper-shaft. The cln tchshipping lever 44 is arranged in an uprightposition on the frame or arch 10 and Within convenient reach of thedriver, and said shi pping-lever is shown as being fnlcrumed at 45 onthe arch. This shipping-lever is fashioned or constructed to provide afork 4G, which is adapted to engage with the driving-clutch 38 betweenits head 39 and the crank-disk 40, and the lever is thus looselyconnected to the drivingclutch in .a manner to permit said clutch torotate with the shaft 33, andat the same time the lever may be operatedto retract the clutch 38 from engagement with theV clntclrface 37, fastwith the shaft 33. The

shipping-lever is normally held by a spring 47 in a position to move thedriving-clutch 38 into engagement With the clutch-face 37 of the shaft33, so that the chopper will be propelled from the shaft 33 through thecrankdisk and the pitman; but it is evident that the operator may movethe lever 44 against the tension of its spring 47 in order to disengagethe clutch from the shaft, thus permitting the shaft` to rotate idly inthe clutch 38.

As one means for driving the shaft 33 I have Y one carrying-Wheel13. Inlien of the sprocketdriving gear I ma'y employ spur-gearing, and in Fig.6 I have represented one end of the shaft 33 as having the spurgear-pinion 53, which meshes directly With a driving spur gear-Wheel54,Which is clamped or fastened to one carrying-Wheel 13. It is evidentthat the shaft bearing 34 for the chopper-driving shaft 33 may be adjusted on the arch or frame 10 to take up slack in the driving-gearbetween the shaft 33 and the gear on the carrying-'wheel 13. The machineis equipped With an ordinary seat-standard 51, bolted to the arch orframe 10, and said standard carries the drivers seat 52, of any suitableconstruetion.

-It is thought that the operation of the machine will be readilyunderstood from the foregoing description taken in connection with thedrawings; but it is desired to remark that the chopping devices mayeasily be thrown out of service When the machine is to be used forcultivating purposes only by adjusting the lever 44 to disengage thedriving-clutch from the chopper-driving shaft 33. It is also evidentthatthe vibration of the rocking chopper-shaft may be varied by shifting theWristpin 42 into one or the other of the apertures 4l in the crank-disk40, said apertures being located at variable distances from the axis ofthe chopper-driving shaft 33.

3. In a combined cultivator and cottonchopper, the combination with anarch or frame and suitable carrying-wheels,of a chopper-shaft, adriving-shaft journaled on the arch vand driven from one of said Wheelsthrough intermediate gearing, said shaft provided with-a fastclutch-face, a driving-clutch provided at one end with a head and at itsopposite'end with a crank-disk, a shipping-lever engaging loosely Withsaid driving-clutch, and a pitman connected with the crank-disk of saidclutch and with the chopper-shaft to positively actuate the latter,substantially as described.

4. In a combined cultivator and cotton chopper, the combination with anarch or frame, theaxles supported thereby and carrying-Wheels on saidaxles, of cross-heads mounted loosely on the axles, a bearing-blockspanning the cross heads and supported thereby, shovel-beams pivoted tothe crossheads and connected by a transverse rail, a chopper-shaftmounted in the bearing-block and the transverse rail to lie between theshovel-beams, and a driving mechanism connected operatively with thechopper-shaft and propelled from one ot' the carrying-Wheels,substantially as described.

5. In a combined cultivator and cottonchopper, the combination of achopper-shaft having a crank, a driving-shaft, a crank-disk revolublewith said driving-shaft and carrying a shittable wrist-pin, and a pitmancon nected to said Wrist-pin and the crank of the chopper-shaft,substantially as described.
